11/2 – Rob’s Monday Mid-Morning “Workweek, November Outlook” Forecast
Continental high pressure continues to build into the Lower Mississippi River Valley with strong cold air advection. The center of the pressure dome is likely to settle along the I-20 corridor tonight and remain in place through Tuesday. As this air mass begins to moderate, it merges with a larger north Atlantic high-pressure to become an extension across the gulf states by Wednesday. Optimal overnight cooling will take place tonight after winds relax to provide cold temperatures in the lower 40s, perhaps an isolated 38-39F in the more interior drainage prone locations. Warming trend gets underway Tuesday afternoon and continues Wednesday.
With easterly flow regime established by Thursday, this regime should persist through the weekend. An easterly wave, quite likely an inverted trough extension from now Hurricane Eta, traverses the east and central gulf waters to bring a focusing mechanism for convection worthy of mention Saturday. Warming trend started earlier in the week carries through the weekend with no frontal passage anticipated through next Sunday.
